Waist-to-Hip Ratio Calculator for Women
Divide waist circumference by hip circumference to screen central fat distribution and interpret the result in context.
Waist-to-Hip Ratio (Women)

How this is calculated
Formula: Waist-to-hip ratio = waist circumference ÷ hip circumference
Waist and hip measurements must use the same unit, so inches or centimeters produce the same ratio.
The waist is measured at the protocol’s specified site and the hips around the widest buttock circumference. Small changes in tape placement can change the result.
Common thresholds are population screening references, not diagnoses. Menopause, pregnancy, ethnicity, body shape, and medical history affect interpretation.
Common WHR screening context for women
| Ratio | Common interpretation | Caution |
|---|---|---|
| Below 0.80 | Lower central distribution | Does not guarantee low health risk |
| 0.80–0.84 | Intermediate range | Review other risk factors |
| 0.85 or higher | Higher central distribution | Often used as an elevated-risk threshold |
Measure consistently
Tips
- •Use a flexible non-stretch tape over skin or thin clothing.
- •Stand relaxed with feet together and breathe normally.
- •Keep the tape horizontal without compressing the skin.
- •Take two measurements and repeat if they differ.
- •Do not apply standard thresholds during pregnancy.

Frequently asked questions
A ratio below 0.85 is often used as a lower-risk screening threshold, but some guidelines subdivide lower values. Health cannot be judged from WHR alone.
Waist-to-hip ratio is a screening estimate, not a diagnosis. Thresholds vary among guidelines and populations, and the measure is not appropriate during pregnancy. Discuss personal cardiovascular or metabolic risk with a clinician.
